Analysis
HTS 2931.90.15 covers sodium tetraphenylboron under heading 2931 (other organo-inorganic compounds).
Within this group the rate runs from duty-free to 6.5%. Compared with 2931.90.70 (n,N'-Bis(trimethylsilyl) urea…), which pays duty-free, a misclassification either way moves the duty by 5.8 percentage points.
Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 12 others can enter duty-free instead of paying 5.8%. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.
The general duty rate is 5.8% of the customs value, which is in the middle of the rates in chapter 29 (65th percentile of 1050 lines with an ad valorem rate). On a shipment valued at $10,000 that is $580 in duty before any Chapter 99 additions or preference claims.
Census statistics map these goods to NAICS 325199 (All Other Basic Organic Chemical Manufacturing), an industry of 894 US establishments employing 77,304 people. That concordance is how imports of this line are compared with US output.
